JP2511104B2 - Access right control method for electronic mail - Google Patents

Description

The present invention relates to an access right control system for accessing a mailbox required for sending and receiving electronic mail and the like.

[Prior Art] Since a communication device using UNIX as an operating system has conventionally provided a mail command related to a mail service, there is less demand for creating a unique e-mail program, and the mail service should be performed. There is also little information available. In the above command, the contents are limited because the mailbox has a simple structure in the past. Note that UNIX is a program development system developed at Bell Laboratories to provide a good development environment with a programming language in a series of software development processes that develop software and maintain it.

Next, the operation of the mail command will be described. Regarding access right control, it is natural that only the system administrator can view or update the mailbox.
Generally because the management depends on the "login name"
Considering the Japanese name in terms of OA services, it has a lack of versatility. In addition, the mailbox structure is a simple structure and is not hierarchical, so it is not suitable for handling a large amount of mail from the viewpoint of search performance when a large number of people are targeted, and more In the case of emails with attributes, it is difficult to manage because they do not have separate storage structures.

[Problems to be Solved by the Invention] From the above-mentioned point, the conventional mail command is suitable only for the purpose of handing down messages for each user in a stand-alone manner. It was necessary to consider constructing a mailbox structure when handling as. Therefore, the conventional access right control method has a problem that the access right of the mailbox cannot be freely set and the access right control cannot be improved.

The present invention has been made to solve the above-mentioned problems, and it is possible to freely set the access right of a mailbox and to perform an advanced access right control. The purpose is to provide a control method.

[Means for Solving the Problems] The access right control system according to claim 1 of the present invention is a file server 12 and a plurality of workstations 7, 9, 11 ...
In a communication system in which and are connected via a network (LAN1) to send and receive mail, a mailbox 13 is provided in the file server, and the mailbox 13
Is a mail for each user who stores the mail for each user under the management by the Japanese name (“Japanese owner name”) corresponding to the “login name” of each user who uses the above workstation. Boxes 14, 15, 16 ... Are created so that each user can send mail to another person's mailbox and each user cannot refer to or update another person's mailbox. It is characterized by inputting a Japanese name for mail operation from each user and controlling the access right between the above-mentioned mailbox and each user's workstation according to the mail operation indicated by this Japanese name. It is a thing.

The access right control system according to claim 2 of the present invention is characterized in that a notification board mailbox accessible to each user is created in the mailbox 13.

[Operation] When the Japanese name related to the mail operation from each user is input to the file server, the file server causes the mail server between the mailbox and each user's workstation according to the mail operation indicated by the Japanese name. Control access rights. When a Japanese name for operating the notice board mailbox is input to the file server, the file server controls each user to access the notice board mailbox.

One of the plurality of communication devices N1, N2, N3 is assigned as a file server for storing a mailbox and mail. In this embodiment, the communication device N1 is a file server.

FIG. 2 is a conceptual block diagram for explaining transmission / reception of mail in this embodiment. In the figure, in the file server 12, mailboxes 14, 15 and 16 are created corresponding to each user. The mailboxes 14, 15, 16 are created in the main storage device 3 shown in FIG. The sender 6 sends a mail by the workstation 7 to the mailbox 15
Send to. The reader 8 circulates the mail 16 and the mail by the workstation 9. The recipient 10 retrieves the mail from the mailbox 16 by the workstation 11.

FIG. 3 is a diagram for explaining the configurations of the mailbox and the email. FIG. 4 is a diagram showing an example of setting the access right of a mailbox and a mail, and shows the UNIX name, Japanese name, owner, and access right of directories and files.

Next, the operation of this embodiment will be described. In FIG. 3, the mailbox comprises a cabinet, a first folder and a second folder.

mfdir stores attributes such as the Japanese name of each directory. The mail is stored under the second folder. Therefore, the mailbox has a hierarchical structure of directories and files in consideration of user protection when developing an email service, manages it based on the Japanese name, and performs access operations based on the Japanese name. Configured to do.

As a result of the mailbox being configured in this way, the following condition setting can be performed by the access right control (control by the basic processing device 2) based on FIG.

(1) Mail can be sent to any mailbox.
(2) You can refer and update your own mailbox.
